Inaccurate and imprecise AA Grendel barrel.

[EPeterson]

Did you assemble it yourself? And if so, how confidant are you that it was assembled and torqued down properly? I had a Lilja 6.5 barrel that a LGS put on. After mediocre results at the range, I put the barrel back on using loctite and torqued it down to proper specs. It now shoots very well. That being said, my fist AA barrel had gouges cut into the rifling and I never got consistent accuracy till I replaced it with said Lilja barrel.
Here's the marks, the barrel came off a AA 6.5 Tactical upper.
